Title: Improvements in the separation from gas mixtures of substances which have a high vapour pressure at their melting point
IPC: B01D53/14
Filed: 1930-08-20
Abstract: <PICT:0361914/III/1> Gaseous mixtures are separated by treatment with a solvent at a temperature below the triple points of the constituents to be dissolved.  The dissolved gases are then separated by slowly heating the solution with or without reduction of pressure. The Figure illustrates the application of the process to the separation of a mixture of hydrogen, nitrogen, methane, and acetylene resulting from the production of acetylene from methane in the electric arc.  This mixture compressed to 10 atmospheres at A and freed from water and lubricating oil in the cooler B is cooled in the apparatus C, D to -80 DEG  C., and is treated in the washing tower E with acetone at a temperature of -90 DEG  C.  The tower E is cooled by means of boiling ethylene.  The solution passes to the chamber F where the pressure is released causing evolution of the dissolved hydrogen, nitrogen, or methane, and finally passes through the fractionating column M in which its temperature is raised.  Fractions rich in acetylene, alkylene, and diacetylene are withdrawn at o, q, and r respectively.  The purified solvent withdrawn at t is admitted at l to pipes arranged in the column and so undergoes heat-exchange with the descending liquid.  It subsequently returns to the washer E. To prevent contamination of the solvent by condensed moisture the gas should be thoroughly dried before treatment and ice-dissolving substances such as alcohol may be added to the acetone.  A second example relates to the separation of a mixture of hydrogen, nitrogen, carbon dioxide, and ethylene by treatment with acetone at -85 DEG  C. and 10 atmospheres pressure.

Title: Towel cabinet
IPC: A47K10/28
Filed: 1923-10-09
Abstract: 221,099. Borroughs, J. N. Oct. 9, 1923. Roll holders and cases.-A towel cabinet is arranged to release, so that it may be withdrawn from a roll, a predetermined length of towel each time a press-button release device is momentarily operated. The roll of towelling rests loosely in a bracket 10, and the towel passes overthe upper near edge, over a corrugated rubber delivery roller 11, out of the cabinet through a slot 20 formed in the cabinet door, re-enters the cabinet through a slot 21 below the bottom edge of the door, and passes over a take-up roller 16, the soiled towel accumulating in the lower part of the cabinet. Pressure rollers 12, 17 keep the towel in contact with rollers 11, 16 respectively, depending wire loops 23 resting in grooves in the roller 16 prevent the soiled towel from rewinding on roller 16, and a partition 22<a> prevents moisture from the soiled towel from rising to the clean towel above. Rollers 11, 16 have gear wheels 26, 25 respectively meshing with an idler 27 which in turn drives a control gear 28. Drive is obtained by drawing the towel from the cabinet against roller 11. Gear 28 carries a stop bar 29 the outer end of which is laterally resilient to allow flexure away from the plane of the wheel. A pivoted detent 31 is urged towards gear 28 by a spring 33, and may be moved away therefrom by pressure on the knobbed outer end of the rod 34. Detent 31 has a lateral tongue 32 adapted to engage the stop 29, and is of tapered form so that the member 29 is flexed laterally as it aproaches the tongue 32. When detent 31 is moved outwards by actuating rod 34, member 29 springs back laterally under the detent and so remains clear of the tongue 32. Gear 28 is thus freed to make one revolution and allow withdrawal of a predetermined length of towel at each operation of rod 34.

Title: Method for the production of levulose
Inventor: HOLSTEIN ARTHUR G
IPC: C12P7/58
Filed: 1962-07-02
Abstract: Levulose is obtained from sucrose by fermenting invert sugar, formed from sucrose, in the presence of glucose oxidase and air and at a pH of 4.5-6.5 (maintained by the addition of an alkali or alkaline earth metal salt) the gluconic acid formed being separated in the form of its salts, filtering the solution which contains levulose, concentrating the solution to a specific gravity of not less than 1.45, diluting the remaining solution with an alcohol and allowing it to cool until the crystallization of the gluconic salt is completed, stripping off the alcohol, diluting the solution with water, treating it with activated carbon, passing solution successively through a cation exchange resin and an anion exchange resin until the anionic content of the solution is reduced to below 15 grains per gallon, concentrating the effluent from the ion exchange, diluting it with an alcohol, allowing it to cool and removing the levulose crystals formed. Preferably the fermentation in the presence of glucose oxidase is carried out at 28-32 DEG  C.  The sucrose is inverted to glucose and levulose by any suitable means, for example by acid hydrolysis using hydrochloric or sulphuric acid, or by enzymatic action by treatment with a hydrolase such as invertase or lactase.
Patent GB-785147-A (GB)
Title: Glyceride molecular rearrangement process
IPC: C11C3/10
Filed: 1955-09-02
Abstract: In the catalytic re-arrangement of fatty acid radicals in a mixture of glycerides, the mixture of glycerides is treated with a catalyst comprising a sodium-potassium alloy containing, by weight, 75-3 per cent of sodium and 25-97 per cent of potassium, and the mixture is agitated at a temperature not higher than 120 DEG  F. so as to disperse the alloy throughout the mixture and effect molecular re-arrangement.  The dispersion and the re-arrangement are effected at a temperature at which the alloy remains liquid but not above 120 DEG  F.  Animal, vegetable and marine fatty oils and fats may be treated such as tallow, palm oil, soyabean oil, linseed oil, coconut oil and particularly lard and cottonseed oil.  The alloy preferably contains 50-15 per cent by weight of sodium and 50-85 per cent of potassium; for general use, an alloy of 50 per cent of sodium and 50 per cent of potassium may be used. Some excess of alloy may be used if the oils and fats contain impurities, but these are preferably first removed.  The amount, based on the oil, is preferably within the range of 0.2-1 per cent by weight, calculated as sodium.  The alloy is introduced as a liquid into a liquid mixture of the glycerides and is dispersed in the form of droplets averaging not more than 50 microns in diameter.  The process may be batch or continuous.  The reaction may be accompanied by precipitation of solid glycerides formed during the course of rearrangement.  The re-arranged products are then treated as usual to inactivate the catalyst, e.g. by adding an excess of water, and are finally filtered to remove suspended soaps.ALSO:Alloys for use in the treatment of oils and fats (see Group III) contain 75-3 per cent of sodium and 25-97 per cent of potassium, more particularly 50-15 per cent of sodium and 50-85 per cent of potassium.  An alloy of 50 per cent each of sodium and potassium is preferred.  The alloys are of low melting point, the lowest melting alloy containing about 77 per cent of potassium and 23 per cent of sodium and melting at about 10 DEG  F. The alloys may be made by passing sodium vapour through fused potassium chloride and fractionating the mixture of sodium and potassium vapours so obtained.
